What’s so special about these showers?
According to Cook, having multiple meteor showers occur at the same time is a common phenomenon. “For example, during the Perseids, you have the remnants of the Southern Delta Aquariids going on,” he said.

Right now, the Alpha Capricornids, the Southern Delta Aquariids and Perseids are all active and while the Perseids is not at its peak , you might still see some of its meteors this week. There’s also the possibility of seeing 10 to 12 meteors that aren’t associated with any of these showers, according to Lunsford.

Both the Alpha Capricornids and Southern Delta Aquariids become visible annually when Earth passes through debris fields left by two Jupiter-family comets: 169P/NEAT (Alpha Capricornids) and P2008/Y12 (Southern Delta Aquariids). Cook also noted that, each year, “we’re passing closer to the core of the material that produces (the Alpha Capricornids) shower and in 200 years, it’ll be the strongest shower that’s visible from Earth. It’ll actually produce more than 1,000 (meteor streaks) an hour, which is quite a bit stronger than it is now.”
For those interested in contributing to astronomers’ understanding of meteors, this week presents the perfect opportunity to count how many meteors you see in the night sky and report them to places like the American Meteor Society.

Lunar and solar eclipses in 2025
Two eclipse events will occur as summer ends.
A total lunar eclipse will be visible in Europe, Asia, Australia, Africa, parts of eastern South America, Alaska and Antarctica on September 7 and 8, according to Time and Date.
A lunar eclipse occurs when Earth passes exactly between the sun and the moon, throwing the latter into shadow and making it appear darker or dimmed.
When the moon sits in the darkest part of Earth’s shadow, the sun’s rays bend around Earth and refract light on the moon’s surface, which gives it a reddish hue, according to London’s Natural History Museum. Some people call the result a “blood moon.”
Two weeks after the total lunar eclipse, a partial solar eclipse will be visible in parts of Australia, the Atlantic, the Pacific and Antarctica on September 21.
Solar eclipses occur when the moon moves between the sun and Earth, blocking part of the sun’s surface from view, according to NASA. This creates a crescent shape — as if something took a “bite” out of the sun. |
